Y., minor to Southern Kraft Corporation, New York, N. Y., a corporation of Delaware Application July 24, 1933, Serial No. 681,870 Claims. (01. 229-16) My present invention relates to improvements in paper packages or cartons suitable for packing fruits, vegetables or the like for shipment and sale. More particularly my invention com- 5 prehends the provision of a carton or package which is adapted to display the contents thereof when offered for sale.

In my prior U. S. Patent No. 1,741,369 granted December 31, 1929 it is pointed out that in packages or cartons of the character recited above it is very desirable and advantageous to confine the contents of the package under moderate pressure, thereby not only firmly securing and preventing injury to the fruitor other comv modity thus packaged but insuring that the package or carton will present a full and tightly packed appearance when ofiered for sale in spite of any shrinkage of the total volume of the contents as may occur between the time the carton go is packed and the time of sale. It will be understood, of course, that no intent to deceive is contemplated or possible, as the commodity packaged is either sold on a bulk weight or count basis. Nevertheless, successful merchandising demands a package having a well filled appearance.

My present invention contemplates and has for its primary object the provision of an im- 1 proved carton or package of the character indic'ated, capable of being formed from a single continuous sheet of paper, and a blank therefor.

Another feature of my present invention is the provision of a carton and blank therefor of the character indicated, having provision for filling the same from the bottom as well as for adjusting the interior volume of the carton in a simple and eificient manner. The blank is designed for ventilating the contents of the carton, for holding the contents securely in place and for facilitating rapid packing of the carton with fruits and vegetables of difierent sizes and in diiferent quantities. In this respect my invention constitutes an improvement over my copending application, Ser. No. 631,647, filed September 3, 1932.

These and other objects. of my invention will be more clearly understood from a study of the following description taken in conjunction with the attached drawing in which Fig. 1 is a plan view of a pre-formed sheet of paper or blank adapted to be folded to form a carton of the character indicated above;

Fig. .2 is a perspective view of the formed carton;

Fig. 3 is a bottom plan view thereof; and

Fig. 4 is a sectional view taken along the lines 4-4 01 Fig. 2.

Referring now more particularly to Fig. 1 it will be apparent that my carton is formed from a single continuous sheet of paper of suitable 5 character, having a cover panel A, side panels B, C, D and D, insert flaps E, E, F and F, and a bottom panel G. Although any suitable material may be used, I have found that the type of material known as single or double faced kraft 1U corrugated board is preferable, since this material is strong, rigid and relatively thin for its stiiiness.

The cover panel A is divided by score lines IO, N, l2 and I3, forming a rectangle, the corre- 15 sponding sides of which also form sides of the side panels B, C, D and D. Inwardly of the score lines II), II, l2 and I3, the cover panel A is provided with perforations or cuts l4, l5, l6 and I1 which define a mutilatable display panel 20 substantially rectangular in shape and surrounded by a border or marginal section l9. The display panel is cut out as at 20 to provide a handheld to assist in the easy removal of the panel by the retailer. The corners of the rec- 25 tangular display panel are joined to the corresponding outer corners of the cover panel A by diagonal score lines 2|.

The bottom panel G adjoins side panel 0 along score line 30 extending parallel to score line I2. 30

That portion of the bottom adjacent score line 30 is separated from insert flaps F and F by means of convergent slots 3|. The score line 32 ,is provided parallel to and relatively closely spaced from the score line 30. A score line 33 35 extending parallel to score lines 30 and 32 is provided near the outer end of the panel G to form a flap 30. One or more cut-out portions 34 is provided in each side wall of the panel 9 and a suitable handhold 35 is formed in the bottom 40 proper. By the provision of the parallel score lines 30, 32 and 33 the bottom may, in packaging certain types of fruit, be positioned as indicated in Fig. 4. I

When my carton is to be formed and filled, the 45 insert flaps E, E, F and F are first bent at substantially right angles to the corresponding side side panels D and D are then bent along the score lines II and I3, respectively, until they meet the insert panels E, F, E and F. The panels D and D are then fastened by means of staples 38 or other suitable fastening means to the adjacent insert flaps E, F and E, F, respectively, care being taken to insure that the outer sides of flaps E, F, E, F are in abutting relation. The carton thus formed is ready to be filled.

I have found that the mere act of forming and securing the carton as above described tends to cause the cover panel A to bulge upwardly to some extent, slight bends being made along the score lines 2|, thus raising the display panel above the outer edges of the cover panel A. This bulge is sometimes further accentuated when the carton is packed.

In the event that the fruit or other commodity placed within the carton is not of sufficient bulk completely to fill the carton, the bottom panel G is bent along score line 30. That portion of panel 9 defined by score line 32 being turned inwardly of and adjacent to side panels C to which it may be fastened by means of staples 31 or other suitable fastening means. The flap 38 defined by score line 33 is then bent downwardly to contact against side panel B and is secured thereto by staples 39 or other securing means.

The bottom panel G is so positioned with respect to the remaining portion of the carton that it acts through the medium of the contents of the carton to create or accentuate the bulge in the cover panel, thereby raising the display panel about the outer edges of the cover panel and giving the carton a well filled appearance. In the event, however, that the fruit to be purchased fills the carton, the bottom panel G is bent along the score line and the flap 38 is bent upwardly and fastened to the outside wall of the panel B.

It will be noted that with the bottom panel in closed position and fastened to the side panel B the slots 28 formed in the blank provide ventilating openings 40 in the upper and lower corners of the carton which permit circulation of air and maintain the fruit or other contents in a fresh condition. I have thus provided openings of a sufllcient size to provide ventilation and which can be formed in the blank without the use of expensive stripping machinery. It is to be understood, however, that the size of the openings may be changed if small fruits such as blueberries are packaged.

For the purpose of protecting and retaining the contents of the carton when the display panel is removed I have provided a sheet 22 of cellophane or other transparent or translucent ma- I terial, of a size and shape intermediate those of the display panel and the entire cover panel. This window sheet is attached to that surface of the cover panel destined to become an interior surface of the carton when the blank is folded and is secured in place by means of a substan tially continuous strip 23 of adhesive material which surrounds the display panel I8. The cellophane window is attached to the blank by an automatic operation although it is obvious that any desired method of securing said window to the blank may be utilized.

The side panel B adjoining the cover panel A along the score line In terminates at score lines 24 and 25, marking the juncture of the panel B with the side insert flaps E and E, respectively. Similarly, the side panel C terminates at score lines 26 and 21, marking the juncture of the panel C with the side insert flaps F and F, respectively.

The side panels D and D are separated from the flaps E and F and from E and F respectively by slots 28. Score lines 24 and 25, and 26 and 21, are somewhat convergent, thereby providing for a carton of tapered form, as will be apparent from an inspection of several figures and the descriptive matter hereinbelow. Similarly, the slots 28 separating flaps E and F and E and F are somewhat convergent, thereby providing for the tapering of the side walls D and D. The inner corners of the end flaps E, E, F and F are provided with diagonal cuts 29 which are so designed that when the carton is folded into form the outer sides of flaps E and F and E and F will abut each other, as is clearly shown in Fig. 4. By this construction the cubical contents of cartons produced from blanks of the same configuration will be identical. By this construction my improved package will meet the requirements of the trade and will insure a fair and exact measure to the purchaser.

As hereinbefore stated, my carton and the blank from which it is formed are preferably manufactured from paper or fibre of sufficient strength and rigidity to prevent injury to the contents thereof under the ordinary conditions of shipment and storage, and of a material which will prevent the bulge of the side walls of the container under normal conditions. Preferably I employ that material which is generally known as double faced corrugated kraft board.

When the filled carton is placed on display and offered for sale, the retailer may remove the display panel l8 by inserting a finger through the opening 20 and then bending the display panel upwardly along the perforation line M. This will cause the display panel to break away from the cover panel and in this manner a prospective purchaser is afforded a good view of the contents of the carton through the cellophane window without permitting the contents to become bruised, exposed to contamination or otherwise damaged. If desired, the bottom panel G may likewise be provided with a display panel similar to the panel l8, and the same is true of the other sides of the carton, more particularly the panels B and C. As in the case of the top display panel each of the display panels should be provided with a window pane of cellophane or other transparent material.

While for packaging fresh fruit and vegetables I prefer to use the tapered carton hereinabove described, it is to be appreciated that for many purposes a tapered carton is unnecessary, and by dispensing with the convergence of the side walls the carton may readily be made rectangular in shape.

It will therefore be obvious to those skilled in the art that my invention is susceptible of considerable modification in detail without departing from the essential teachings thereof and my invention is therefore not to be limited to the details of the preferred example given above by way of exemplification and illustration, but may variously be embodied within the scope of the claims hereinafter made.

I claim:
